The process of chemical cycling is known as a biogeochemical cycle because it
a. takes place over a long period of time.
b. involves both living and nonliving components.
c. absorbs the chemical involved from the sediment.
d. withdraws the chemical from the atmosphere as a gas.

Correct B). Involves both living and nonliving components.

The biogeochemical cycle is a pathway through which the chemical substances move through the abiotic and biotic compartment of the earth. There are several types of the biogeochemical cycle which are known to recycle chemicals back on to the earth. These include carbon, hydrogen, sulfur, nitrogen, oxygen etc.

It operates as a part of the ecological system. All the chemical elements occurring in an organism are a part of the biogeochemical cycle. Apart from being a part of living organism these also cycles via the abiotic factors of the ecosystem such as water, land, and air.

Hence, the correct answer would be option B.
